ABSTRACT:
A method and apparatus are disclosed to reduce the amount of unstripped hydrocarbon flowing to the regenerator in a riser reactor FCC unit. The catalyst stripper section is heated by indirect heat exchange with a mixture of hot regenerator flue gas and regenerated catalyst. In the preferred embodiment, the regenerator is operated under partial combustion conditions and the resulting carbon monoxide-containing flue gas is burned in a catalyst stripper heat exchanger.
